更改python中的字符串列表

Question

I am trying to change this list

['AAAAA   4 2 1 2 4 2 4 4 5 2 2 1 5 2 4 3 1 1 3 3 5',
 'BBB     5 2 1 2 4 5 4 4 1 2 2 2 4 4 4 3 1 2 3 3 2',
 'K       4 1 2 1 2 1 2 5 1 1 1 1 4 2 2 1 5 1 3 4 1']

to something that looks like this

AAAAA -- [4, 2, 1, 2, 4, 2, 4, 4, 5, 2, 2, 1, 5, 2, 4, 3, 1, 1, 3, 3, 5]
BBB -- [5, 2, 1, 2, 4, 5, 4, 4, 1, 2, 2, 2, 4, 4, 4, 3, 1, 2, 3, 3, 2]
K -- [4, 1, 2, 1, 2, 1, 2, 5, 1, 1, 1, 1, 4, 2, 2, 1, 5, 1, 3, 4, 1]

i have tried multiple ways and cant figure it out

Answer 1

You just need to split the elements in each string, take the first element and set it as key of the dictionary, and convert the rest of the elements to integers, and store as values:

list_ = ['AAAAA   4 2 1 2 4 2 4 4 5 2 2 1 5 2 4 3 1 1 3 3 5',
 'BBB     5 2 1 2 4 5 4 4 1 2 2 2 4 4 4 3 1 2 3 3 2',
 'K       4 1 2 1 2 1 2 5 1 1 1 1 4 2 2 1 5 1 3 4 1']
dict_ = {}
for string in list_:
    alpha, *numbers = string.split()
    dict_[alpha] = [*map(int,numbers)]

for alpha, numbers in dict_.items():
    print(f"{alpha} -- {numbers}")

Output:

AAAAA -- [4, 2, 1, 2, 4, 2, 4, 4, 5, 2, 2, 1, 5, 2, 4, 3, 1, 1, 3, 3, 5]
BBB -- [5, 2, 1, 2, 4, 5, 4, 4, 1, 2, 2, 2, 4, 4, 4, 3, 1, 2, 3, 3, 2]
K -- [4, 1, 2, 1, 2, 1, 2, 5, 1, 1, 1, 1, 4, 2, 2, 1, 5, 1, 3, 4, 1]

If you want to go fancy:

generator_ = (f"{alpha} -- {[*map(int,numbers)]}" for alpha, *numbers in [l.split() for l in list_])

print(*generator_, sep = '\n')

Answer 2

If you want to reproduce what you asked in the question:

x = ['AAAAA 4 2 1 2 4 2 4 4 5 2 2 1 5 2 4 3 1 1 3 3 5', 'BBB 5 2 1 2 4 5 4 4 1 2 2 2 4 4 4 3 1 2 3 3 2', 'K 4 1 2 1 2 1 2 5 1 1 1 1 4 2 2 1 5 1 3 4 1']

for elem in x:
  split = elem.split(" ")
  print("{} -- {}".format(split[0],[int(i) for i in split[1:]]))

This:

• Loops through the list x
• Splits its items into a separate list split
• Separates first element from rest with a "--" when printing

---

Or using a dictionary:

x = ['AAAAA 4 2 1 2 4 2 4 4 5 2 2 1 5 2 4 3 1 1 3 3 5', 'BBB 5 2 1 2 4 5 4 4 1 2 2 2 4 4 4 3 1 2 3 3 2', 'K 4 1 2 1 2 1 2 5 1 1 1 1 4 2 2 1 5 1 3 4 1']

# Create dictionary following above logic
d = dict()
for elem in x:
    split = elem.split(" ")
    d.update({split[0] : [int(i) for i in split[1:]]})

# Loop through its keys and values and print as needed
for k, v in d.items():
    print("{} -- {}".format(k, v))

Output:

K -- [4, 1, 2, 1, 2, 1, 2, 5, 1, 1, 1, 1, 4, 2, 2, 1, 5, 1, 3, 4, 1]
AAAAA -- [4, 2, 1, 2, 4, 2, 4, 4, 5, 2, 2, 1, 5, 2, 4, 3, 1, 1, 3, 3, 5]
BBB -- [5, 2, 1, 2, 4, 5, 4, 4, 1, 2, 2, 2, 4, 4, 4, 3, 1, 2, 3, 3, 2]

Answer 3

inputlist=['AAAAA   4 2 1 2 4 2 4 4 5 2 2 1 5 2 4 3 1 1 3 3 5', 'BBB     5 2 1 2 4 5 4 4 1 2 2 2 4 4 4 3 1 2 3 3 2', 'K       4 1 2 1 2 1 2 5 1 1 1 1 4 2 2 1 5 1 3 4 1']
for item in inputlist:
  item_to_list=item.split(" ")
  temp_list=[int(i) for i in list(filter(None, item_to_list[2:]))]
  print("{0} -- {1}".format(item_to_list[0],str(temp_list)))

Output:

AAAAA -- [4, 2, 1, 2, 4, 2, 4, 4, 5, 2, 2, 1, 5, 2, 4, 3, 1, 1, 3, 3, 5]
BBB -- [5, 2, 1, 2, 4, 5, 4, 4, 1, 2, 2, 2, 4, 4, 4, 3, 1, 2, 3, 3,2]
K -- [4, 1, 2, 1, 2, 1, 2, 5, 1, 1, 1, 1, 4, 2, 2, 1, 5, 1, 3, 4, 1]

Answer 4

x = ['AAAAA 4 2 1 2 4 2 4 4 5 2 2 1 5 2 4 3 1 1 3 3 5', 'BBB 5 2 1 2 4 5 4 4 1 2 2 2 4 4 4 3 1 2 3 3 2', 'K 4 1 2 1 2 1 2 5 1 1 1 1 4 2 2 1 5 1 3 4 1']

for i in x:
    i = i.split(' ')
    tmp = {i[0]:[int(items) for items in i[1:]]}
    for i, j in tmp.items():
        print(f"{i} - {j}")

Output:

AAAAA - [4, 2, 1, 2, 4, 2, 4, 4, 5, 2, 2, 1, 5, 2, 4, 3, 1, 1, 3, 3, 5]
BBB - [5, 2, 1, 2, 4, 5, 4, 4, 1, 2, 2, 2, 4, 4, 4, 3, 1, 2, 3, 3, 2]
K - [4, 1, 2, 1, 2, 1, 2, 5, 1, 1, 1, 1, 4, 2, 2, 1, 5, 1, 3, 4, 1]

Answer 5

Try this:

name=["AAAAA 4 2 1 2 4 2 4 4 5 2 2 1 5 2 4 3 1 1 3 3 5",
      "BBB 5 2 1 2 4 5 4 4 1 2 2 2 4 4 4 3 1 2 3 3 2",
      "K 4 1 2 1 2 1 2 5 1 1 1 1 4 2 2 1 5 1 3 4 1"]


for item in name:
   thelist = list(map(int, ','.join(item.split(' ')[1:]).split(',')))    
   print(f"{item.split(' ')[0]} -- {thelist}")

output:

AAAAA -- [4,2,1,2,4,2,4,4,5,2,2,1,5,2,4,3,1,1,3,3,5]
BBB -- [5,2,1,2,4,5,4,4,1,2,2,2,4,4,4,3,1,2,3,3,2]
K -- [4,1,2,1,2,1,2,5,1,1,1,1,4,2,2,1,5,1,3,4,1]

Answer 6

you can make a dict, and also use that dict to get your specific output if that's what you want:

assuming your list is called full_list

lists = [sub.split() for sub in full_list]
keys = [l[0] for l in lists]
vals = [list(map(int,l[1:])) for l in lists]
d = {k:v for k,v in zip(keys,vals)}

if desired to get that specific output:

for k,v in d.items():
    print(f'{k} -- {v}')

output:

AAAAA -- [4, 2, 1, 2, 4, 2, 4, 4, 5, 2, 2, 1, 5, 2, 4, 3, 1, 1, 3, 3, 5]
BBB -- [5, 2, 1, 2, 4, 5, 4, 4, 1, 2, 2, 2, 4, 4, 4, 3, 1, 2, 3, 3, 2]
K -- [4, 1, 2, 1, 2, 1, 2, 5, 1, 1, 1, 1, 4, 2, 2, 1, 5, 1, 3, 4, 1]
